and the detection module is used for detecting the protocol to be tested according to the test command.
8. The apparatus of claim 7, further comprising:
and the checking module is used for checking the protocol document and determining that the protocol document is a correct protocol document.
9. The apparatus of claim 7, wherein the detection module further comprises:
the sending unit is used for sending the test command to the equipment to be tested;
a receiving unit, configured to receive a response message to the test command sent by the device under test;
and the detection unit is used for detecting whether the protocol to be tested is correct or not according to the response message.
10. The apparatus of claim 9, wherein the detecting unit is further configured to compare the response message with a predetermined judgment condition, determine that the protocol to be tested is correct if the comparison result is consistent, and determine that the protocol to be tested is wrong if the comparison result is inconsistent.
11. The apparatus of claim 10, further comprising:
the second generation module is used for generating a visual interface according to the protocol document;
and the searching module is used for searching the protocol to be tested for realizing the error through the visual interface.
12. The apparatus of claim 9, further comprising:
the device comprises an acquisition module and a communication link, wherein the acquisition module is used for acquiring the communication link, and the communication link is used for determining the mode of sending the test command to the device to be tested by the test platform.
